Take off forend and barrels, then take off the buttplate and unscrew the tang bolt that is in the stock. My memory escapes me, but I believe it is an allen head or torx. The trigger guard is held in by a short protrusion or pin. That should do it. Oh, the stock may be a bit tight, so be careful taking it off. You dont want to slip or rapidly pull it off in the wrong direction, you might chip or crack the stock that way.
